LEA — Daucus carota subsp. sativus

Summary

DCAR_017310, also known as DcLEA, encodes a dehydrin family protein on carrot chromosome 5. The product possesses lipid, phosphoinositide, phosphatidylglycerol, phosphatidylserine, phosphatidate, and metal binding activities. This gene is associated with the acquisition of desiccation tolerance, cold acclimation, response to cold, response to abscisic acid, response to thirst, defence response to fungi, somatic embryogenesis, seed development, syngamy, sucrose transport, protein denaturation, and response to 1-aminocyclopropane-1-carboxylic acid. It localises to the vesicle membrane, membrane, cytosol, cytoplasm, and nucleus. DcLEA has been connected to callus induction, seed maturation, photosynthetic rate, freezing stress tolerance, cold tolerance, drought response, salt and osmotic stress tolerance, membrane stability, and seedling establishment. Studies of related genes in other species link the family to hydrogen peroxide accumulation, ABA sensitivity, and drought stress resistance.
